1. How do you use the Pokémon Center script? I can make a custom heal script, but I can't get it so you go to a Pokémon Center when you die, instead you end up in map 0.0. I tried copying the level scripts from a Pokémon Center in vanilla Fire Red, but nothing :/

2. How exactly do you use the Wild Pokémon level editor? Here's the script I used:
#dynamic 0x100000
#org @start
setvar 0x4051 0x202
release
end

According to the instruction manual, (i think) this should make it so wild pokemon will be the same level as my strongest pokemon + 2 levels, but nothing happens whether i put it in a level script or a floor script :/
